Before saying my opinion about this exact drama I would like to say that I'm a personal fan of Jang Geun Suk's dramas and acting.. his acting is so natural and it gets to me even in his sad scenes you can feel how realstic his sadness is this Drama is no different for him he's acting is still A+ for me ok now about THIS exact Drama! first the story: the material of the story is really good and it actually is different somehow and by the means of different is that the story is almost what seems like an adventure for the protagonist and personally I like these kinds of stories the character development for the main character (Dok go ma te) is logical and I felt like as a watcher that I'm understanding each thought and each move by the main character like I'm in his shoes which in turn made me think that the character development was actually good and it led me to respect him by the end of the drama can't say the same thing about the heroine as much though I hated how clingy is she to him..she was more like a stalker than a lover and in a creepy way it didn't last long in the drama luckily but I had to say that it was a turn off the plot twists specially in the end were average I expected some and I didn't expect the rest with a series filled with lots of plot twists like this it actually added more to the story and prevented me from getting bored that I actually waited each day how things ended up I give the story 6.5 because even though the story had a good material but sometimes there were some cliches specially in the end and I found it a bit cheesy also the author could have done better with the heroine's character development and for the whole characters mainly Acting: As I said in the beginning of the review I love Jang Geun Suk's acting mainly and this drama wasn't any different he did a good job plus he fits the character and he's already used to play the heart throb guy character in most of his dramas so it fits him a lot as for IU She's good as a comedian like always..she did a good job with portraying this stupid clingy heroine (hahaha JK!) the rest of the crew were amazing and personally the best acting goes for Han Chae Young I liked how she played the pretty and calm but dangerous kind of woman and of course Kim Bo Yun was a great antagonist I actually hated her I give the acting 7.5 because I think they could've done better though Music: I know when the music is good when I'm like (when I'm done I'll search for it to download it) and also I keep unconsciously humming it since I didn't do that then I didn't like it so I give it a 4 it was the not bad type but I heard way better Rewatch or not? : I'm not the kind of person to rewatch a drama but if I had to say it would be no because it just didn't click with me that's all overall: the drama was decent and it wasn't boring at all I recommend it to who like dramas that has main character who's aiming for a traget and goes for an adventure to find out how to get to it and also if you like lots of plot twists and surprises this drama's for you finally hope this review was useful and doesn't contain spoilers
